<em>By adding the amplitude of the two waves </em>
<h3><u>Explanation;</u></h3>
<em><u>Wave is a transmission of a disturbance from one point to another. </u></em>Transmission of waves involves transport of energy from one point called the source to another.
<em><u>A characteristic of wave in which two waves meet each other is called an interference. </u></em>When interference occurs it may either be constructive or destructive. When two waves are in sync with each other and occupy the same place at the same time is called constructive interference. <em><u>The amplitude of the resulting wave is the sum of the two original waves. For constructive interference the amplitude is normally larger than the original.</u></em>
<span>When two waves are in sync with each other and occupy the same place at the same time, a constructive interference occurs. To get the resulting wave, the amplitude of each wave is added to produce a wave the represents the result of the constructive interference.</span>
